This invention relates to brakes and more:

particularly to operating levers therefor.

A major object of the invention is to provide a stamped steel operating lever.

An important object of the invention is to provide. a stamped steel lever comprising two stampin s welded or otherwise secured tother t at joint being of such a character t at the finished product will, not require burnishing. M a. A further object of the invention is to provide a stamped lever comprising two stampings welded together to provide a hollow lever possessing great strength and rigidity.

Still a further object of the invention is to provide a lever comprising two stampings fitted and welded together, one of the stampings extending over or fitted around the other to provide a smooth unbroken operating surace. 4

Other objects will appear from the following description taken in connection with the drawing, which forms a part of this specification. and in which:

Figure 1 is a side elevation of the front axle of a motor vehicle havingswivelled thereto a spindle supporting a brake and an operating lever for the brake; t

Figure 2 is a top plan view of the lever; and

Figure 3 is a section substantially on line 3-3, Figure 2.

Referring to the drawing for more specific details of the invention, 10 represents the head of an axle having swivelled thereon a spindle 11 supporting a brake support 12. As shown, an operating shaft 13 is positioned for rotation in the backing plate or brake support and suitably secured to the operating shaft '13 is a lever or crank 14. Positioned on the axle adjacent the head is a boss 15 ings welded together as at 19. These stam ings are substantially alike and vary on y in detail, as for instance, the end portion 18 on one of the stampings is formed to extend over or to fit around the other stamping as having mounted therein a pivot pin 16 and positioned for movement on the pivot pin 16 is an operating lever 17.

As shown, the lever has a rounded end portion 18 adaptable for engagement with the lever or crank 14 and the force applying end of the lever is extended downwardly substantially at right angles to the body protion thereof.

The lever 17 is constructed from two stampindicated at 20, so that a smooth unbroken engaging surface'may be attained and yet great strength and rigidity maintained in thestructure as a whole by reason of the wedging or bracing effect obtained in this particular structure. This is one of the most important factors of the invention, in that it provides -a "smooth surface for engaging thecrank on the operating shaft and b reason of this smooth surface will not nee finishing 'or burnishing during the, course of manufacture.

It is to be observed that the stampings are so formed that when assembled, the fulcrum and the force applyin end'of the lever are materially strengthene byfthe flanges 21 and 22 engaging the pivot .pin 16 and a reach rod, not 'shown, res ectively. 1

Although this invention has been described in connection with certain specific embodiments, the principles involved are susceptible of numerous other applications that will. readily occur to ersons skilled in the art. The invention is, t erefore, to be limited only als indicated by the scope of the appended c aims.

- Having thus described the various features of the invention, what we claim as new and desire to secure by Letters Patent is 1.-A lever comprisin two longitudinally extending generall c annel-shaped parts permanently secure concave face to concave ace, and each forming one side of the lever and said lever being formed with at least one of its ends out of line with the lever body and with one of said parts extendin across the end of the other at said end of t e lever to provide an unbroken ball shaped thrust surface. I

2. A lever comprising two longitudinally extending general y channel-shaped parts secured face toface, and formed with a air of registeri semi-cylindrical openings ormed respective y in each of said parts and jointly forming an opening for a fulcrum pivot,

ooonm said parts each forming one side of the'lever and one being longer than the other nncl overgfing the other to form n smooth unbroken shaped thrust ortion at the end thereof. In testimony w ereof, we have hereunto signed our names.

WILLIAM J. ANDRES.
